OTRAM Step by Step Timing Belt Replacement Video Instructions - DIY (Toyota 2UV-FE, 4.7l V8)

[BnvS]

Dear Friends, Here is yet another timing belt installation DIY step by step you can follow. In my case I used Otrams Videos which were very helpful in getting the TB removed and installed back up.

I took the time to get the time stamp from each step of OTRAM's videos so you can click on specific time stamp and jump to that step.

Additionally I tried to document all the Nuts/bolts/screws, screw sizes and torque settings for each components that needs to be taken off.

The full link to the file is below - Toyota 4.7l V8 Timing Belt Replacement Procedure. The link also has some more images that would be valuable in the installation process to understand. I.e. the placement of certain nuts/bolts etc.

Timing Belt Spreadsheet - Please comments and I'll add any additional comments to spreadsheet as needed

I will copy the steps below just so if this file is not accessible then you can at least see the steps.

Let me know what you think.

Thanks to all who have helped via this forum.

Official TB instructions from a 2006 Tundra also attached below (should be very similar to the LC/LX)

P.S. BTW I am not sure if Otram is on these forums or not I see @OTRAMM so hope thats you buddy.

16	15. Remove Fan bracket - Remove AC comp Side bolts in front - 2x14mm 4in Top and bottom front bolts (see pics) Loosen back bolt on AC to pivot it enough to remove fan bracket	Toyota 4.7 Timing Belt Part 1 (updated) - https://youtu.be/4dO8KW1-NQs?t=710 Toyota 4.7 Timing Belt Part 1 (updated) - https://youtu.be/4dO8KW1-NQs?t=726 (Ac bolt locations) Toyota 4.7 Timing Belt Part 1 (updated) - https://youtu.be/4dO8KW1-NQs?t=745 (Back bolt location - DO NOT TAKE IT OUT - Just loosen it)+ Toyota 4.7 Timing Belt Part 1 (updated) - https://youtu.be/4dO8KW1-NQs?t=799 (top front bolt location)		2x14mm bolts on front side of ac compressor, LOOSEN only back bolt 1x14mm on ac compressor rear (for me it was eaiser to take drivers tire off and through that side space using Small/medium Swivel socket remove both the bottom front ac bolt and loosen the back bolt) Just keep bolts/nuts together on the fan bracket here to track them - TOO many bolts and nuts hear to track, 12mm and 14mm here
17	16. - Loosen AC compressor	Toyota 4.7 Timing Belt Part 1 (updated) - https://youtu.be/4dO8KW1-NQs?t=745		- 2 x bolts on ac front (Top & Bottom - Make sure you do not remove the AC bracket bolt which is close to the bottom front bolt) and -- Only loosen rear bolt 1 x bolt the rear bolt to pivot AC (Come from driver side opening) this is still a PITA but can be done. Use Small/medium Swivel socket - uplug the ac connector & bend bracket to take it out
18	17. HERE YOU ALIGN THE TDC (Top Dead center)	Toyota 4.7 Timing Belt Part 1 (updated) - https://youtu.be/4dO8KW1-NQs?t=950		crankshaft bolt - 22mm socket on to move TDC - This has to be aligned depending on your Year the TDC arror has to be pointed differently - First rotate it to cranckshaft mark to 0 on the timing cover mark. - Ensure the marks align with 0 and 2 camshaft mark lines (NOT with T) if not aligned move it another rotation to get the 0 (timing cover & crankshaft) and lines aligned on 2 camshaft gears and camshaft cover - then for 2000-2001 LC move crankshaft another 50 deg to so crankshaft mark aligns with middle bolt of the red pully- https://youtu.be/4dO8KW1-NQs?t=1024
19	18. Remove Crankshaft pulley	https://youtu.be/4dO8KW1-NQs?t=1068		- Ensure you are still aligned with the Crankshaft mark so your valve and such are aligned - Use torque gun to take the crank bolt out (check alignment before fulling taking out) - I used a wd40 or similar oil to spray in the middle where the bolt is of the crank pulley and let it sit for few minutes, Then used short wooden 2x4 and hammer and hit the crank pulley at different angles to get it lose. Keep at it, its not the fastest method. You may have to do this a few times to work.
20	19. Remove camshaft timing plastic cover	https://youtu.be/4dO8KW1-NQs?t=1230		4x10mm bolts
21	20. Remove timing sensor guide plate	https://youtu.be/4dO8KW1-NQs?t=1267		it is concave when removed so ensure it’s the same position with putting it back in
22	21. Removing Plastic Triangle	https://youtu.be/4dO8KW1-NQs?t=1296		my car did not have this - Ensure Timing belt is still aligned properly
23	22. Remove the Hydraulic timing belt tensioner	https://youtu.be/4dO8KW1-NQs?t=1332		2x12mm bolts from the bottom - loosen them evenly
24	24. Remove Timing belt off	https://youtu.be/4dO8KW1-NQs?t=1417
25	25. Remove Idler pully #2 (Red one)	https://youtu.be/4dO8KW1-NQs?t=1437		1x14mm bolt
26	26. Remove Tensioner Idler Pully #1 black - above timing belt tensioner	https://youtu.be/4dO8KW1-NQs?t=1485		10mm hex - MAKE SURE YOU GET the WASHER and kept it safe
27	27. Slide the Timing belt pully off	https://youtu.be/4dO8KW1-NQs?t=1518
28	28. Remove Cam Sensor trigger	https://youtu.be/4dO8KW1-NQs?t=1562		1x12mm nut top , 1x12mm long stud bottom lower hold of sensor
29	29. Remove Water Pump - need to twist/wiggle it out at times	https://youtu.be/4dO8KW1-NQs?t=1549		too many bolts/nuts to keep track, so just take it out and keep the nuts and bolts on old water pump. And put while putting in new water pump just transfer bolt/nuts from old to new pump

Good job, thanks. This should be linked into some of the other timing belt threads so that people can find it.

[e9999]

Very nice!
I added this to the FAQ, don't change the thread name in case it throws the link off.
If somebody wants to add some time estimates for the whole thing and/or main steps, that would be great!

 

[BnvS]

Thanks @e9999 I'll make sure I'll keep the topic the same...

I didn't add time estimates b/c time is really dependent to the person's experience. This took me 4 days to do at a steady pace.. If I have to do it again I would be able to do it in say 2 days. But I am sure someone more experienced may be able to do it in one day.. If in doubt slow and steady wins the race..I say.

 

[OffRoadRN]

Thank you so much!

A note on step 7 of the install: you should seal the tensioner pulley pivot bolt threads.; if you don't you get an oil leak. FSM specifies adhesive including blue loctite 242. The updated video(engine out of truck) doesn't have this step but the old video(part 2) did.

This is a step I think most people skip (myself included in the past) that causes a very slow oil leak, that often gets diagnosed as a front crank seal leak or oil pump leak.

You can also buy a new bolt that has sealant on it already I believe. Seems like a very odd design to have the hole threaded through the oil pump, but I assume it was a packaging thing.

Hi @BnvS Thank for sharing, awesome.

I do have a LC100 built 11/1999 and have a question for you.

You are listing also the TDC. For the LC 1998-2002 it's 50deg BTDC (BEFORE) - see pic

In another thread I found the information it is 50deg ATDC (AFTER) - see pic

May you or anyone here verify what's the correct TDC setting for my Land Cruiser respectively for the year 1999 please.

 

[Malleus]

This is exactly why you need to use the service manual for your year model and not rely on internet posts for specific repair advice; from the 1999 Land Cruiser service manual (which is in the Resources forum for free download):

 

[2001LC]

In the 98-05 USA 4.7L which are the non VVTi. The 50 degree, BTDC (befor) or ATDC (after), we can ignore this procedure. It's so valves don't hit piston tops. We've found they don't, even with belt off we can spin crank or cams in non VVTi engine.

We can just set on marks and remove belt. But so often when we do. The cam(s) are sitting, with valve spring tension of some valves on some cam lobes. The slightest jar, and cam(s) move on their own from valve spring pressure. No big deal in the NON VVti.

I check timing, to make sure belt correctly place on (Engine "Timed"). Before I put on lower timing cover. With hard marks. Which is crank sprocket notch to oil pump dimple. This is same as zero on plastic cover to line on harmonic balancer (large lower pulley). Plastic cover, isn't as accurate, as may have shifted a tad. It also nice to make sure timed, before getting cover on.

We match cam sprocket to straight line, while crank sprocket on the mark. This is done after spinning crank CW 720 degrees. Note: Belt marks, will no long line up.

 

[2001LC]

VVti 4.7L (2006-07) we do set timing belt differently. During disassembly and assembly. This is where the while stub on lower cover and "T" for cam marks, come into play. Also we've a different mark on oil pump we use for hard mark during belt install.

This is 50 degrees ATDC. The VVTi engine is an interference engine. So we must take added precautions. In these VVti, I do not spin crank or cams with belt off.

White stub on lower cover

The while stub on cover, corresponds to oil pump mark (a square quartered off) when crankshaft key pointing to it

The crankshaft key, also is corresponds to sprocket V notch.

Which is also what the second set of double lines on new belt is for.

Which we can use, to keep cams from turning by valve spring tension in non VVTi also. Then, crank marks align with square on oil pump (while stub of lower cover)

Here we see VVT cams marks to the "T's" A must when service VVTi timing belts.

But I still check timing to the "I" after spinning crank 720 degrees CW when new belt on, in VVTI or non. They're the easiest to read and most accurate.

 

[2001LC]

I do not remove or loosen AC compressor rear bolt. No need. Just bend the bracket blocking in fan bracket, out of the way.
I get to lower front AC bolt with long extension w/14mm universal socket. Turn wheels, to the left helps. Slight lift of vehicle also helps.

Torque to 36ft-lbf

Slip socket and extension, PS between boot and PS hard line.

 

[2001LC]

I almost never reuse old fan bracket (FB). I like new OEM (Toyota Aisin) fan brackets, the best

Any oil seen coming from FB seal, sound from or play in bearing, replace FB.
Metal fillings in dust. Very bad bearings.

Signs of oil on seal, replace it.

 

[2001LC]

Most block have pitting under water pump gasket, in aging 4.7L. I create a patch, to fill pits.

 

[2001LC]

Notice yellow paint on every bolt/nut. My most used tools during and assemble: Torque wrench and a paint stick.

Torque and paint. No paint, get out the torque wrench again:

BTW: The 2005 FSM has a wrong torque spec of 53ft-lbf, for the vane pump. Correct is 13ft-lbf.

Thank you for all this, I'm about to embark on this job soon
